Emergent headwater types for watershed monitoring, research, and planning Emergent headwater types for watershed monitoring, research, and planning
Headwaters—that is headwater streams and the watersheds they drain—strongly influence water quality, ecosystem services, and hydrologic connectivity, yet remain poorly mapped, monitored, and understood at large spatial scales. Using available spatial data to classify headwater “types” could therefore enhance the utility of sparse monitoring data to advance research and watershed planning...
A hybrid approach for revealing headwater hydrology A hybrid approach for revealing headwater hydrology
Coordinated work to compile existing data and apply models pairing physical understanding with machine learning could substantially improve streamflow predictions for little-known headwater basins.
Creating 3D point clouds, digital elevation models, and orthomosaics from historical aerial imagery through structure from motion aided photogrammetry Creating 3D point clouds, digital elevation models, and orthomosaics from historical aerial imagery through structure from motion aided photogrammetry
Detailed and accurate historical data are crucial to characterizing landscape change, whether it is caused by natural phenomena or of anthropogenic origin. Aerial imagery has been periodically collected by government and nongovernment agencies, for a broad range of purposes, since the early 20th century. The acquisition of aerial images involves using standardized equipment with large...
Science
Synthesizing methane fluxes, isotopes, and microbiomes to better understand the dynamics and consequences of permafrost thaw in a sensitive and strategic Arctic
This interdisciplinary working group will bring together leading experts in microbial ecology, biogeochemistry, isotope science, remote sensing, and ecosystem modeling to synthesize how Arctic ecosystems are responding to changes in microbial and landscape processes.
Towards an integrated multi-scale understanding of dryland plant traits with application to land management
This proposed project brings together scientists, federal agencies, and land managers to improve the monitoring and management of dryland ecosystems in the western United States.
A digital twin to accelerate volcano science and unify geodetic and seismic observations
Emerging computational and data assimilation approaches and increasing data volumes imply an opportunity to greatly accelerate both fundamental volcano science and hazard assessment and forecasting.
